Question: A 20 cm diameter, 2.0 kg solid disk is rotating at 200 rpm. A 20 cm diameter, 1.0 kg circular hoop is dropped straight down

A 20 cm diameter, 2.0 kg solid disk is rotating at 200 rpm. A 20 cm diameter, 1.0 kg circular hoop is dropped straight down onto the rotating disk and sticks, as shown 1 below. The moment of inertia of a solid disk around its center of mass is I = MR2; NI the moment inertia of a hoop around its center of mass is I = MR. Before: After: w = 200 rpm 20 cm AL Mloop = 1.0 kg M disk = 2.0 kg |Symmetry axis
